The Andromeda device runs an experience tailored for its unique form-factor, which is built on top of Windows Core OS. This tailored experience is known as Andromeda OS and includes no legacy UIs and bloat. Microsoft is doing the exact same thing with Surface Hub 2, which also runs a custom tailored version of Windows Core OS known as Aruba and built specifically for that large collaborative device form factor.

Therefore, it's important to stress that Andromeda OS is unlike any version of Windows 10 available on the market today; it's an entirely new Windows OS experience powered by CShell that's built from the ground up for mobile dual-screened multitasking. Because of this, Microsoft needs more time to ensure the OS is well-baked.

Bowden's article is probably the closest to the current state of Andromeda.
